Portal Cavernoma

Portal cavernoma corresponds to the abnormal development of a venous network whose caliber is initially microscopic, with hepatopetal portal blood flow. It is a consequence of chronic portal thrombosis in a healthy or slightly fibrous liver. The causes are essentially those of portal thrombosis. However, portal thrombosis remains an undetermined cause in 50% of the cases. The clinical manifestations of cavernoma reflect extrahepatic portal hypertension and are exceptionally biliary. The diagnosis of portal cavernoma is radiological. Ultrasound Doppler and CT confirmed the diagnosis. MRI offers a better analysis of biliary impact. The treatment is essentially medically based on anticoagulants. Recording to surgery was reserved for complications.
